A CIVIL DESIGN NARRATIVE

1.0 GENERAL

1.01 The purpose of this project’s civil work is to install a new storm drainage pipe to eliminate flooding in the building currently caused by an old pipe at the cooling tower level. Due to extensive corrosion of the existing pipe and the deterioration of the bituminous lining, re-grading the area to create a new low point, installation of a new shallow inlet, and installation of a new drainage pipe that will connect the inlet to the existing stormwater system will be necessary. In addition to this work, we will be looking to improve the existing parking and loading area conditions, adding permanent security fencing and clearing of existing vegetation where necessary.

2.0 SCOPE OF WORK

2.01 Civil scope of work will include the following items:

• Analysis and design of proposed grades

• Design of Concrete Pavement

• Installation of Drainage Improvements, including new shallow inlet, 12”

RCP diameter drainage pipes, two shallow catch basins and a new drainage manhole.

• Restoration of Concrete Pavement at Proposed Grade

• Removal of corroded corrugated pipe. Existing wall openings will be closed (coordinated with architecture).

• A section of 6” cast iron building storm drain pipe which has broken will be replaced between the building wall and storm manhole (coordinated with plumbing).

B ARCHITECTURE DESIGN NARRATIVE

West Point Central Plant was built in 1908 and is in need of selective upgrades to best fulfill its mission. The building is in operation 24/7, 365 and presents many safety and environmental hazards. The facility is 50,050 sf and is staffed by (5) supervisors and (24) operator / mechanic personnel.

2.1 ROOF

The existing asbestos containing roof will be scrapped off mechanically with dry methods. This process will vibrate the existing light weight cinder roof deck and generate dust and debris. The contractor will be required to contain the dust and debris to the area above the bottom chord of the roof truss. An allowance of 1,000 sf of roof deck will be carried for roof deck replacement.

Loose material at the underside of roof deck will be removed, the remaining material cleaned and sealed with a vapor permeable coating such as Prosoco

BMC II, or equal. A vapor drive and dewpoint analysis is included as an appendix. New roofing will be as indicated below.

a. Low slope roof areas – built-up asphalt roofing on rigid insulation on existing roof deck.

b. Maintenance Shop Tower Corridor Roof – Asphalt shingle, Ice and

Water Barrier, 5” Composite Roofing Panel, 3” Rigid Roof Insulation, Existing T&G decking.

2.2 SKYLIGHT

The existing (2) 20’ x 20’ skylights will be replaced with (2) 20’ x 54’ removable translucent self-supporting ridge roofs. A daylight modeling report is included as an appendix.

2.3 WINDOW REPLACEMENT

Refer to drawings A-1201 thru A-1203.

2.4 MASONRY / EXTERIOR WALLS

Refer to preservation scope and drawings A-410 thru A-416

2.5 DOORS

The existing exterior doors at high visibility locations will be replaced with wood grain FRP doors in conformance with West Point guidance. At low visibility locations, galvanized hollow metal doors will be provided.

Interior doors will be replaced with either solid core wood doors or hollow metal doors depending on the location, with hollow metal doors used

C PRESERVATION DESIGN NARRATIVE

1.0 REPOINTING

1.1 The mortar of the granite walls varies in condition, with an estimated 25-30% requiring immediate repointing due to failed or open mortar joints. The remainder is in fair condition. Some parts will require repointing in the near future as the thin layer of mortar from the most recent repointing campaign is likely to continue failing at an increasing rate. Given these conditions and the significant effort and expense in materials, personnel, equipment, etc.

required to access and repoint even limited portions of the walls, the recommended approach is that the mortar joints in the granite walls should be repointed 100%. This will also ensure a uniform mortar appearance. Note that on the chimney tower repointing may be limited to areas in poor condition as total repointing of the tower elevations would result in a visually jarring juxtaposition with the existing mortar that will remain on immediately adjacent tower surfaces that are out of scope. Rake all mortar joints of the granite walls to a depth of at least twice the height of the joint; where mortar deterioration is deeper than this ratio, granite should be deep-repointed or removed and reset. Use a lime-based mortar with higher permeability than the granite.

1.2 The brick of the inner face of the parapet wall requires 100% repointing due to failing mortar and previous repointing using inappropriate mortar that is less permeable than the bricks, causing spalling. Rake all mortar joints of the brick parapet to a depth of at least twice the height of the joint; where mortar deterioration is deeper than this ratio, bricks should be deep-repointed or removed and reset. Use a lime-based mortar with higher permeability than the bricks.

1.3 Mortar samples will be analyzed to determine the precise constituents of the mortar mix, and new mortar will be placed to ensure the relative hardness and permeability of the mortar is compatible with the stone and brick. The new mortar will also match the existing in color and texture. Sampling will be executed in the construction phase.

2.0 SEALANT

2.1 Varying degrees of existing sealant failure at masonry openings, copings, and upward-facing masonry joints is almost universal across all elevations. Given this widespread failure and in order to maintain the uniformity of appearance, integrity, and lifespan of the joints, all joints with sealant, whether intact, failed, or missing, will have the remaining sealant removed, joints cleaned, and new backer rod and tooled sealant applied. Refer to Masonry Restoration drawings for approximate areas requiring resealing.

3.0 MASONRY REPAIR

3.1 Repair cracked lintels, sills, and other limestone elements using precise crack pinning and dutchman repair methods.

100% Submission - Page 8

3.2 Provide dutchman repairs to areas of detached limestone at corners of windows on the east elevation and of the window on the west elevation of the maintenance shop tower by patching using appropriate mixes and/or replacement pieces of limestone that match the existing.

3.3 Remove all abandoned metal fixtures (hooks, brackets, pipes, etc.) affixed to masonry and patch holes appropriately with mortar, epoxy, or dutchman repairs or stone replacement. Refer to Masonry Restoration drawings for locations of abandoned metal fixtures.

3.4 Remove an abandoned storm line in the east elevation of the tunnel passage leading to the maintenance shop tower. Infill the resulting masonry opening with granite masonry units that match the existing adjacent masonry in appearance and composition. Set the new units in a random ashlar pattern within the opening; do not disturb adjacent masonry or attempt to tooth new masonry into adjacent as this may cause masonry damage or structural issues.

3.5 The existing concrete west entry platform and stairs are deteriorated beyond repair and require reconstruction. Rebuild in existing configuration with granite stairs and concrete platform. Retain and stabilize existing cheek wall.

Refer to structural drawings.

3.6 Remove and salvage part of south wall of maintenance shop tower to expose embedded metal wall frame (refer to drawing 3/A-416). Probes conducted revealed that the metal wall frame is corroding, which has displaced adjacent masonry and caused joint separation. Remove rust from frame back to bare substrate, apply rust inhibitive coating, and reassemble wall placing each unit of salvaged masonry back in its original location. Use a lime-based mortar more permeable and less hard than the masonry.

3.7 The existing stone and brick wall extending south from the maintenance shop tower will be removed and salvaged down to sound masonry construction

(approx. 3’-6”), then reassembled using salvaged original masonry units and new masonry units to match the existing in appearance and composition.

Provide new limestone coping to match existing coping at upper roof parapets and provide new zinc-tin coated copper through wall flashing.

Temporarily support existing utilities/systems infrastructure to facilitate masonry restoration work.

3.8 Remove metal catwalks, railings, and brackets attached to west side of maintenance shop tower and tunnel passage and restore in a shop by stripping, patching, and galvanizing, then re-install.

3.9 Replace spalling bricks at the inner side of the main roof parapet wall in kind with replacement bricks that match the existing in color and composition.

3.10 Replace deteriorated copper flashing between limestone coping and brick/granite of main roof parapet and between limestone coping and granite parapet on two towers (toilet room/stair tower and utilities/break room tower) on south elevation and on chimney (north) tower. Provide new zinc-tin coated copper through wall flashing. Restore to original design specifications by inserting flashing that spans the full depth of the wall with

100% Submission - Page 9 a drip edge on the interior and exterior faces beneath the coping. This will significantly reduce moisture ingress into the masonry of the wall below, mitigating moisture damage. Probes conducted revealed that the coping stones do not currently have any metal dowels connecting them to the parapets. Provide dowel anchors (two per coping stone) set into stone with thimbles soldered to flashing.

3.11 Replace existing counterflashing at all roof parapet walls with new zinc-tin coated copper counterflashing with appropriate pitch downwards to meet roof membrane parapet wall flashing.

3.12 Clean all limestone features and granite walls using the gentlest means possible, beginning with pressurized steam or water with mild detergents.

For more heavily soiled areas for which these methods may be inadequate, the use of chemical cleaners may be considered with the architect’s approval.

If the use of chemical cleaners in addition to water is deemed necessary, the liquid waste from cleaning will be captured and disposed of appropriately.

3.13 Remove two deteriorated brick/CMU doghouse structures along east elevation down to concrete window well. Provide two new doghouse structures. Refer to Masonry Restoration drawing sheet A-415.

4.0 EXISTING BUILDING

4.1 Based on available record drawings, the Power House was built circa 1908 and consists of built-up steel columns and girders with steel beams. The roof was constructed of 7’-0” deep steel roof trusses spaced at 18’-6” O.C. with steel purlins and includes several large skylights. Most of the roof is 3” thick cinder concrete fill but there are areas of metal deck adjacent to the large skylights.

4.2 The Turbine Hall and Coal Bunker floors consist of built-up steel girders and 20” deep beams with a 6-¼" thick concrete slab. The Boiler Room has 15” and 12” deep steel beams with a 3-½" concrete on metal deck. The steel beams are encased in concrete. The basement floor slab below is a 5” thick slab on ground.

100% Submission - Page 11

4.3 In the Turbine Hall, there is an overhead bridge crane with a load capacity of

20 tons. The crane rails are seated on steel girders which are supported inboard of the existing built-up steel columns on steel brackets. The existing column and bracket are encased in masonry.

4.4 The exterior wall consists of stone façade with masonry walls.

4.5 Refer to Field Investigation Report dated December 2022 for additional information.

5.0 STRUCTURAL DESIGN

5.1 Proposed Mechanical Equipment: The existing roof slab and steel roof trusses will be analyzed to determine if they are adequate to support the weight of the proposed mechanical equipment. Lighter equipment may be supported on curbs but heavier equipment will be located on existing steel dunnage, if possible. Supplemental steel will be added to reinforce the existing roof and existing steel dunnage, as needed. New openings in the roof will be framed out in steel.

5.2 Proposed Skylight Expansion: The existing metal roof deck adjacent to the skylights will be removed and the skylight will be expanded. Supplemental steel will be provided to accommodate the larger skylights. Refer to Architectural for additional information.

5.3 Boiler Room Separation: A new 20’-0’ high partition wall will be added to separate the Chiller Room and Boiler Room. The partition will be supported on the existing slab; should the existing slab be inadequate, steel supports will be provided below. The head of the partition wall will be anchored to the underside of the existing roof trusses in the Boiler Room.

5.4 Crane Replacement: The existing 20-ton bridge crane including the crane rails will be removed and replaced with a new 20-ton crane and ASCE 40 rails. It is assumed the existing support girder and brackets will have to be removed and replaced.

5.5 Office and Locker Room: A new two-story office and locker room will be added to replace the existing office in the Turbine Room. The existing one-story structure will be removed. The new structure will be framed with steel columns and beams. The existing slab on metal deck will be removed locally to allow for the installation of the steel columns. A new steel stair will be framed from the second floor to the Engine Room main floor.

E LIFE SAFETY

SUMMARY

Based on the site survey and analysis of existing conditions at West Point Central Plant completed by the Jensen Hughes Team, an overview of the applicable code requirements and existing deficiencies are described herein. As part of the Statement of Work (SOW), it is understood that the project is to comply with UFC-3-600-01, this document is being prepared to summarize the existing areas of the building that do not comply with these applicable requirements as to aid to the development of a scope of work for the current project. All work (e.g., break room renovations) will comply with the requirements of UFC-3-600-01 and thus NFPA 101. This document only addresses existing areas of non-compliance.

APPLICABLE CODES AND STANDARDS

All the recommendations proposed for the report on life safety are referenced from the below-mentioned standards.

• NFPA-101, 2021: Life Safety Code

• UFC 3-600-01: Design: Fire Protection Engineering for Facilities, Change 5, 24

September 2020.

• UFC 1-200-01: General Building requirements, Change 1, 1 October 2020

• NFPA-10, 2022: Standard for the Portable Fire Extinguishers

• NFPA-13, 2019: Standard for the Installation of Sprinkler Systems

• NFPA-72, 2019: National Fire Alarm and Signaling Code

The Central Plant is an existing multi-story building with mechanical and equipment throughout. UFC Section 2-1.2(e) defines this project as a Major Project due to the new installation and work to an existing HVAC system serving areas greater than 5,000 sqft of floor area. This Major Project must comply with the minimum requirements of existing facilities noted in Chapter 34 of UFC 3-600-01. UFC 3-600-01 Section 34-1.2 specifies that the entire facility must comply with the applicable existing occupancy chapter of

NFPA 101, Life Safety Code.

Based on the use of this facility the applicable chapter is NFPA 101, Chapter 40 for industrial occupancies. Specifically, the West Point Central Plant falls into the category of Special-Purpose Industrial Occupancy. This is defined as industrial occupancies that conduct ordinary and low hazard industrial operations in buildings designed for, and that are usable only for, types of operations.

GENERAL MEANS OF EGRESS REQUIREMENTS

The following items describe the general applicable means of egress elements and how they may apply to the West Point Central Utility plant. This list is not all inclusive of all life safety requirements but rather a list of the significant items affecting this building.

Exit Access Travel Distance – In accordance with Table 40.2.6.1 of NFPA 101, a maximum

100% Submission - Page 14 travel distance of 400 feet is allowed in a Special-Purpose Industrial Occupancy building provided throughout with an approved automatic sprinkler system.

Common Path of Travel – In accordance with Table 40.2.5.1 of NFPA 101, a maximum common path of travel distance of 100 feet and a maximum dead-end distance of 50 feet is allowed in a Special-Purpose Industrial Occupancy building provided with an approved automatic sprinkler system. Common path travel is defined as the distance an occupant can travel before, they have the choice of two exits.

Number and Remoteness of Means of Egress - Not less than two means of egress must be provided from every story or section, not less than one means of egress must be reached without traversing another story (NFPA 101 Section 40.2.4.1.1.) A single means of egress is permitted from a story or section in low and ordinary-hazard industrial occupancies, provided the exit can be reached in the distance permitted for common path of travel (NFPA 101 Section 40.2.4.1.2). In buildings protected throughout by an automatic sprinkler system, the minimum separation distance between two exits or exit access can not be less than one-third the length of the overall diagonal dimension of the building or area served.

Headroom Clearance – A minimum headroom clearance of 6 feet 8 inches is required within all means of egress per NFPA 101 Section 7.1.5.

Stair Dimensions – The building utilizes industrial equipment access platforms and stairs as means of egress. These platforms and stairs must be in accordance with NFPA 101, Table 40.2.5.3.1. The existing main exit stairs are subject to the requirements of NFPA

101 Table 7.2.2.2.1.1(b). Reconstruction of these stairs would be subject to the dimensional criteria for new stairs, NFPA 101 Table 7.2.2.2.1.1(a).

Protection of Exit Stairs – Vertical openings, such as exit stairs must be protected with fire-resistance rated construction unless permitted for the special-purpose industrial use per NFPA 101 Section 40.3.1. NFPA 101 40.3.1 is not applicable, therefore the main exit stairs require a fire-resistance rated separation of 1-hour per NFPA 101 Section 7.1.3.2.1.

Discharge of Exit Stairs Through Interior Building - The main exit stair is required to terminate at a public way or directly at the exterior. Exit stairs are permitted to discharge through an interior level or exit discharge, when not more than 50-percent of the number

100% Submission - Page 15 of exits do so (NFPA 101 Section 7.7.2).

Fire Escape Ladders - Fire escape ladders are permitted as a means of egress from

Industrial occupancies when used in accordance with NFPA 101 Section 7.2.9. NFPA 101

Section 7.2.9 limits the use of fire escape ladders to an occupant load of three persons who are capable of using the ladder.

Exit Signage – Exits must be marked with signage that is readily visible from any direction of exit access (NFPA 101 Section 7.10.1.2.1). Exit access must be marked such that no point within the access is more than 100 feet from the nearest sign. Exit signs must either be externally illuminated with artificial lighting or must be internally illuminated to ensure continuous illumination.

Emergency Illumination – Means of egress components such as stairs and exit access must be provided with emergency lighting to assist in egress during a loss of power.

Emergency lighting can be provided via back-up/ emergency power or via battery back-

up. A minimum of 0.6 foot-candles at the floor level for a period of 1 1.2-hours is required

(NFPA 101 Section 7.9.2.1.2).

EXISTING MEANS OF EGRESS CONDITIONS

The West Point Central Utility Plant is a multi-level building. The eastern portion of the building extends from a Basement Level (not shown below) to Level 5. This section of the building contains many equipment platforms and access stairs. The western portion of the building extends from Level 3, which largely contains piping, to Level 5. The only access from the east/west portions of the building are via Level 5 and through the main exit stairs.

All geographic orientations are per north, page right.

LEVEL 1 (East Only)

Level 1 is a limited access area due to the grade and elevation change. There is one exterior door which provides direct access to the exterior. A long accessway provides access to the workshop and existing egress ladder.

100% Submission - Page 17

LEVEL 2 (East Only)

Level 2 contains two main levels (shown in yellow and blue). The control room is indicated in the lighter blue shade. The main exit stair terminates at this level, adjacent to the primary exit which provides direct access to the exterior. This is the only exit on this level without traversing to Level 1 or above.

100% Submission - Page 18

LEVEL 3 (East and West)

The eastern portion of Level 3 contains largely equipment platforms and access stairs

(shown in purple). There is one access to the main exit stair from these areas. Access to Level 2 is also via the open/equipment stair in the central portion of this space.

The western portion of Level 3 contains piping and has limited vertical clearance. There are two exit access stairs that provide access to Level 4 above. This portion of the building can also access the main exit stair which discharges in the eastern portion of

Level 2.

100% Submission - Page 19

LEVEL 4 (West Only)

This area has access to an exterior exit at the grade level via a short set of half level access stairs. There is also access to the main exit stair which discharges on Level 2 of the eastern portion of the building.

100% Submission - Page 20

LEVEL 5 (West and East)

The eastern portion of Level 5 has access to a central portion of open stairs. These stairs provide access to the exterior door on Level 2. This portion of the building can also access the west portion and the exterior door up the half level access stairs.

The western portion only has a mezzanine (highlighted in green). There is no main exit stair access on this level. The only exit available is the exterior door at grade which requires travel down a small set of access doors.

EXISTING ITEMS OF NON-COMPLIANCE

The following items have been identified as the most significant areas of non-compliance. This list is not exhaustive of all items within the building that may be non-compliant with the applicable codes and standards, but rather a summary of the most significant items that may be corrected within the scope of this project.

1 Level 1: Fire Escape Ladder and

Headroom

The fire escape ladder is only permitted to serve an occupant load of less than 3 people. The occupant load of the workshop is higher. Additionally, the access door does not maintain a 6 ft. 8-inch headroom clearance.

2 Level 1: Common Path of Travel

The distance to the Level 1 exterior door from workshop is more than

100 feet when the use of the fire escape ladder is not considered.

[ Not shown on Level 1 Plan above]

3 Level 2: Common Path of Travel

The distance that occupants must travel from the (north) portion of the building to have a choice to egress via the exterior door OR at an adjacent level exceeds 100 feet.

It has been noted that a ship’s ladder on this level was abandoned some time prior.

[ See Level 2 Plan Above]

4 Level 2: Travel through Level of Exit Discharge

The main exit stairs terminate at the building interior at Level 2. Travel from the stairs to the exterior door is required. For some building areas, this is 100% of the number of exits provided, which is more than

50% permitted.

5 Level 3: Headroom Clearance at Exit Stair

The exit access door providing access into the main exit stair from

Level 3 does not have adequate headroom.

6 Level 3: Means of Egress Remoteness

Level 3 only has access to the main exit stair and the central equipment stair. Both these stairs discharge to the same point on Level 2. The means of egress are not remote from each other.

[ See Level 3/2 Plans Above]

7 Level 4: Headroom and Egress from Break Area

The existing egress from the Level 4 breakroom (west) is under an exit access stair without adequate headroom. A double egress door is currently blocked by a refrigerator that provides adequate headroom.

8 General: Piping/Headroom

May means of egress throughout the building do not have 6ft. 8-inch clearance due to piping and other encroachments on vertical clearance (e.g., Level 3 west).

9 Exit Stair: Stair Dimensions for Existing Stairs

The main exit stair width, rise and tread dimensions are not in compliance with the limits for an existing stair.

1 Exit Stair: Protection of Vertical Opening

The main exit stair is not protected with fire-resistance rated construction as the doors onto the stairs have been removed. Fire door assemblies need to be replaced to maintain fire-resistance of stair enclosure.

1 General: Exit Signage Placement and Illumination

Many areas throughout the building do not have adequate directional signage or in some cases signage is not internally or externally illuminated.

1 General: Emergency Illumination

Emergency lighting wall-packs appear to be scarce. Additional emergency wall-packs or integration of building lighting onto back-up power is required.

F FIRE SPRINKLER AND STANDPIPE SYSTEM

The West Point Central Plant has an automatic sprinkler system that has recently been completed. Applicable codes and standards for any sprinkler work in the renovation include the following:

• NFPA-13, 2019: Standard for the Installation of Sprinkler Systems

• International Building Code, 2018.

• UFC 3-600-01: Design: Fire Protection Engineering for Facilities, Change 5, 24

September 2020.

• UFC 1-200-01: General Building requirements, Change 1, 1 October 2020

The Central Plant is protected throughout with an approved automatic sprinkler system.

Where a space is reconfigured (i.e. locker rooms, break rooms) the location of sprinklers will be adjusted to comply with the codes in the NFPA-13, 2019. Additionally, the sprinklers and piping in the north section of the building will be rerouted to accommodate the installation of the new skylights. Sprinkler relocation is also anticipated to accommodate the new wall being installed in boiler room.

The existing sprinkler system including the existing deluge sprinkler system and all the valves and components will remain in operation. There will not be any modification to existing valves in the sprinkler system. The existing water flow switches and tamper switches must be connected to the new fire alarm control panel for monitoring.

The existing roof deck has been indicated to be “cinder” and not capable of supporting the newly installed sprinkler system for the long-term. As part of this project, the sprinkler piping and components currently hung off cinder roof deck will be supported by building steel. Any new sprinkler piping support and hangers must meet the requirements of NFPA-13. Coordination with structural details to facilitate sprinkler pipe hanging is included in 50% design.

As per Section 9-10.2.2 from UFC 3-600-01, there should be a class-I standpipe system installed where all portions of the building cannot be reached from an exterior door in less than 450 feet. At this time, there were no portions of the building that fell into this requirement. However, there is an existing standpipe system that will remain. The existing standpipe connections must comply with the inspection and testing requirements of NFPA-25. It is recommended that hose valve locations be provided with signage for ease of locating.

The existing building does contain many fire extinguishers. Fire extinguisher location and placement will be reviewed and brought up to the spacing requirements of NFPA

10.

3.0 SYSTEM DESCRIPTIONS

3.01 The plumbing work will consist of:

• As part of the roof replacement planned for the upgrade project, new roof drains will be installed, generally in the same location as the existing ones to coordinate with the new membrane roofing system. For areas with flat roofing enclosed by parapet walls (main roof and tower roofs), combination primary/secondary overflow type drains will be utilized to meet the current

100% Submission - Page 28 code intent and provide a means of relief should the primary roof drains become clogged. The primary drain outlet of the new drains will be connected into the existing storm leader, while the secondary overflow drain outlet will be connected into a new secondary leader installed as part of the upgrade project. Additionally, gutters and downspouts will be provided at the edge of the new skylights over the turbine hall and along the edge of the pitched shop tunnel roof.

• New secondary drain leaders will be installed to connect to the overflow roof drain outlets. Secondary drain leaders will be cast-iron pipe run either individually where construction allows or grouped similarly to the primary drainage system. Secondary drain leaders will terminate at the exterior wall

12” above grade with a splash block in a conspicuous location so that facility staff can be alerted to an overflow/clogged drain condition.

• For the new restrooms/locker rooms at the stair tower, the existing sanitary and domestic water plumbing will be completely demolished along with the existing restrooms within the tower back to the sanitary connection leaving the building. New sanitary and domestic water plumbing risers and distribution will be installed for the new restrooms. The existing 6” sanitary connection from the tower to the sewer manhole in the parking lot will be replaced. A new vent stack will be installed at the roof. Domestic hot and cold water will be supplied from the existing building domestic systems through rerouted piping

(existing piping to the tower restrooms is fed through the tower staircase).

Hot water recirculation will be provided for new lavatories and shower.

• The new locker room to be constructed on Level 4 will be provided with new sanitary and domestic cold and hot water piping. The locker room will include lavatories, water closets, a urinal and a shower. The sanitary will be connected into the sanitary system and sewer connection at Williams Road. Domestic cold water will be extended from the existing cold water piping in the lower turbine hall and domestic hot water will be extended from the existing water heater below the locker room. Hot water recirculation will be provided for new lavatories and shower. New plumbing will be provided for the clothes washer to be located in this area. The existing clothes washer, service sink and associated drain pump will be removed from Level 1 of the boiler house.

• The existing steam-fired 65-gallon domestic water heater has a capacity of 189 gallons per hour at 100 degree F rise. With the new restroom/locker room configuration, the estimated peak hot water demand for the domestic fixtures in the facility is approximately 143 gallons per hour at 90 degree F rise. The steam-fired water heater is approximately 3-½ years old. An add alternate will be provided to replace this item in kind. The unit was assessed during the plant shutdown, however, it is not equipment with an anode rod; rather it utilizes a cement line tank. After reviewing with DPW it was determined that replacement of this water heater in-kind will be included as part of the project.

There is also a 50-gallon electric water heater with a 4.5 kW element which is understood to serve as a back-up source of domestic hot water during steam plant shutdowns. This water heater is approximately 13 years old and has a

100% Submission - Page 29 recovery rate of 21 gallons per hour at 90 degree rise. Given its age, the back-up water heater will be called out for replacement. A new electric water heater with a 9 kW element will be provided in its place to provide additional capacity during shutdowns. It may be considered to replace this water heater with one with a capacity better matched to the anticipated hot water demand, however since its primary purpose is as a temporary back-up the additional expense may not be warranted.

• The domestic water piping from the water heater area into the stair tower restrooms is currently run through an open doorway between the stair and the turbine hall basement. This prohibits installation of a fire-rated door to enclose the staircase. It is proposed to reroute this piping through the adjacent wall between the electric cable room and the Level 3 restroom, where it will distribute to the other level restrooms.

• The existing service sink at the tool room (over the pump room/former coal chute) is connected onto a storm drain. The sink will be disconnected from the storm leader and provided piped by gravity to Pump Room SB01 sump basin with a new undersink self-contained pump/basin which will discharge through a pumped drain line into the sanitary connection at the top of the former coal chute.

• It was observed that certain piping sections of the sanitary system on Level 1 of the boiler house were in poor condition. This would include the 6” sanitary drain exiting the building near the doors to the cooling tower yard, which is corroded on both its interior and exterior. Additionally, the sanitary drain from the water softener pit, the 6” sanitary drain serving other drains near the condensate tank and the associated house traps also displayed some corrosion and are proposed for replacement. New traps will be installed at each existing drain, and a drain quench valve will be added for the condensate tank overflow/drain.

• An abandoned (capped) portion of the former combined building drain system along the east side of the boiler house will be disconnected and removed.

• The majority of the existing building storm drains are in good condition and will be retained. However, some debris (roof ballast, leaves, etc.) were observed during scoping and all existing drains will be called for cleaning to clear any debris. One roof drain on the east side is connected into a vent line with a temporary flexible drain hose; this will be corrected and connected into the east storm drain with a new section of pipe. One section of storm pipe at the building exterior was observed to have a crack where the piping exits the building, but it is not obstructed. This section of piping will be called for replacement.

• Where existing fixtures are to be replaced in the same general locations

(breakroom sinks, bathroom under the turbine hall stairs, drinking fountain, etc.) sanitary and domestic water will be disconnected and reconnected.

Sanitary will be replaced to main. Main will be reworked at connection to underground.

• A potential remedy to the stormwater infiltration reported at the steam tunnel will be provided. A sump pump will be provided at the alcove beneath the tunnel where it connects to the central plant building, with a curb between alcove and building to retain water in the pit. The sump pump will discharge into the existing 6” storm drain line which runs through the steam tunnel. This item will need to be coordinated with the steam tunnel repair projects. The sump pump will report status and high level alarm to the BAS.

• A new floor drain, sump pump, cover and controls will be installed at the existing sump pit located at the south tower basement (bottom of coal chute).

This will pump any water that collects in the lower level up to the sanitary connection/MH at the top of the chute. The sump pump will report status and high level alarm to the BAS.

• The existing cooling drain tower will be removed and replaced to accommodate the removal of the corroded corrugated storm drain pipe (see civil).

• The historic air compressor, tank and associated piping (disconnected, non-functional) will be removed to make room for the new tool cage. Final disposition will be per the direction of West Point DPW.
